156 Carcinological Fauna of India. 
inconspicuous, keeping close ‘to the lateral border. Rostrum a non- 
cylindrical bifid tooth, with a smaller spine on either side of its base. 
2nd joint of antenna-peduncle having its antero-external angle produced 
to form aspine. Palate distinctly delimited from the epistome every- 
where except in the middle line. The last pair of legs reach to the end 
of the carpus of the preceding pair. 
Types H. barbata (Herbst) and H. andamanica, Alcock. 
Homotax. Carapace urn-shaped, its greatest breadth being behind, 
across the middle of the branchial regions: the linea anomurica conspic- 
uous, running well inside the lateral border. Rostrum as in Homola. 
2nd joint of antenna-peduncle having its antero-external angle acute, 
but not spiniform. Palate as well demarcated from the epistome in the 
middle line as it is elsewhere. The last pair of legs reach beyond the 
end of the carpus of the preceding pair. 
Type H. megalops, Alcock. 
Paromota Wood-Mason. ‘“ Carapace decidedly macrurous in form,” 
its greatest breadth being behind: the linea anomurica very conspicuous 
and well inside the lateral border. Rostrum a simple cylindrical spine 
of large size, flanked on either side by a single spine of equal or greater 
size. 2nd joint of antenna-peduncle not produced or specially acute at 
the antero-external angle. Palate everywhere well demarcated from 
the epistome. The last pair of legs not reaching beyond the end of the 
merus of the preceding pair. 
Tyres H. cuviert, Roux and H. profundorum, Alcock. 
Subgenus Homola. 
21. Homola andamanica, Alcock. 
Homola andamanica, Alcock, Investigator Deep-Sea Brachyura, p. 7: and Illus- 
trations of the Zoology of the Investigator, Crustacea, pl. xl. fig. 1. 
This may, very possibly, prove the same as Homola orientalis 
Henderson, though it cannot be quite reconciled with the description, 
still less with the figure, of that species. 
In any case it is probably only a variety of Homola barbata, with 
3 good specimens of which—representing both sexes—it has been 
compared. The only differences between it and H. barbata are the 
following :— 
The eyes are more reniform, The second spine of the lateral 
border is just behind the hepatic region. There are spines on the 
posterior border of the meropodites of all four pairs of walking legs.
